[boost] JSON Parser + Boost Fusion + adapted structs

Hi everybody, I am writing a prototype for the JSON parser for the GSoC with the support of Bjorn Reese. When discussing the proposal, Michael Marcin suggested an interface that allows the user to define a struct reflecting the JSON data structure. I have been looking at Boost.Fusion to enable the parser to "fill in" the values in the struct. It looks like I'm after a solution described in the following post: http://stackoverflow.com/questions/13830792/simulate-compile-time-reflection... Could anyone tell me if this is a good starting point, and/or if there are other ways of achieving this. Thank you, Stephan.
